Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 ESM Summary: Several security issues were fixed in libxml2. Software Description: - libxml2: GNOME XML library Details: USN-3424-1 fixed several vulnerabilities in libxml2. This update provides the corresponding update for Ubuntu 12.04 ESM. Original advisory details: ﾃつ It was discovered that a type confusion error existed in libxml2. An ﾃつ attacker could use this to specially construct XML data that ﾃつ could cause a denial of service or possibly execute arbitrary ﾃつ code. (CVE-2017-0663) ﾃつ It was discovered that libxml2 did not properly validate parsed entity ﾃつ references. An attacker could use this to specially construct XML ﾃつ data that could expose sensitive information. (CVE-2017-7375) ﾃつ It was discovered that a buffer overflow existed in libxml2 when ﾃつ handling HTTP redirects. An attacker could use this to specially ﾃつ construct XML data that could cause a denial of service or possibly ﾃつ execute arbitrary code. (CVE-2017-7376) ﾃつ Marcel Bﾃδｶhme and Van-Thuan Pham discovered a buffer overflow in ﾃつ libxml2 when handling elements. An attacker could use this to ﾃつ specially construct XML data that could cause a denial of service or ﾃつ possibly execute arbitrary code. (CVE-2017-9047) ﾃつ Marcel Bﾃδｶhme and Van-Thuan Pham discovered a buffer overread ﾃつ in libxml2 when handling elements. An attacker could use this ﾃつ to specially construct XML data that could cause a denial of ﾃつ service. (CVE-2017-9048) ﾃつ Marcel Bﾃδｶhme and Van-Thuan Pham discovered multiple buffer overreads ﾃつ in libxml2 when handling parameter-entity references. An attacker ﾃつ could use these to specially construct XML data that could cause a ﾃつ denial of service. (CVE-2017-9049, CVE-2017-9050) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 ESM: ﾃつ libxml2ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ ﾃつ 2.7.8.dfsg-5.1ubuntu4.18 In general, a standard system update will make all the necessary changes.
